Analitički modeli probijanja metalnih ploča kinetičkim penetratorom
Slobodan Jaramaz Dejan Micković
The process of penetrating thin metal plates with a
flat-head cylindrical penetrator has been described as well as the most
important analytical models of penetration, paying particular attention to
predefined requirements, basic process mechanisms and key analytical relations
necessary for the realization of appropriate computer programs. The values
obtained by calculations have been compared with the results of the
authors′ experiment. The comparative analysis shows a significant
accordance of the penetration process basic parameters but it also points out
certain constraints of analytical models. The model of deformation waves with a
deformable penetrator is concluded to present the best analytical approximation
of the penetration process. Its modification resulted in an improved penetration
model.
